This inventionrelatesto easement window fastenerr and has relation more particularly i 51to provide novel and improved means where- Y bythe swinging window n sashv may be veffectively held with respect tothe window frame.A

Another obj ect ofthe invention b is to vprovide adevice ofthis kind' wherein the fasten-V er member is carried by. the member of the 4frame ataJ point inwardly of said frame for y holding VAengagement with the out swinging member of the sash whenthe' sash is in closed nposition with respect to theframe. v Y

The invention consists inthe details of construction and inthe combination and ar rangement of the several arts -ofmy improved casement window astener whereby certain importantadvantages are attained and the device renderedsimpler, less expensive and otherwisemore convenient and advantageous for use, as will behereinafter.

more fully set forth. Y

The novelfeatures of my invention'will hereinafter be definitely'claimed.

In order that my invention maybe the better understood, I will now proceed to describe the same with reference to the accom-v panying drawings, wherein i y Figure 1 is a view partly in section and partlyv in top plan illustrating a fastening means for a easement windowV constructed in accordance with an embodiment of my invention;. f Y

Figure 2 is a fragmentary view in perspective illustrating coacting members ofthe window easement and frame and certain of the parts comprised in the fastening means directly associated therewith; Y

n As disclosed in the accompanying draw.

ings, F denotes 'a easement frame'ofrequisite dimensions and design Yand which isadapted sash VW. This sash Wrisadapted to beV 1928. ySerial N0. 289,533.

.hingedly connected in a well known manner with a side or vertical member of the frame 1 foroutward swinging movement with respect to the frame.

The vertical member 1 of the frame F ad-v 55 jacent to the out swingingmember 1a of the sash W at a desired point thereonyand preferably substantially midway of its ends, has

anchored thereto by the screws 2 or the like `an en d portion of av plate 3 extending` within 0 Vthe light area of the frame F and also eX- Vtending inwardly beyond said out swinging member 1when the vsash isvin closed position. The extended portion of the plate 3 or that i portion within the light area of the frame F 05 is provided with an opening 4 through which is directed a shank 5 carried by the central Yportion of the inner face of a head 6.. This shank extends inwardly beyond the late 3 and to said extended portion is suitaEly iiXed'a lfastener member or disc 7. This disc 7 has an arcuate beveled marginal portion 8 substantially equal to a quarter of a circle, said beveled marginal portion 8 constituting 'the working face of the disc 7 i 75 Y The periphery of the disc 7 immediately ad] acent to one end of the face 8 isprovded with an arcuate recess 9 providing spaced shoulders l() which are adapted to have contact with a pin 11 extending outwardly from'. 8o the innerpfaceof the plate S'whereby the eX- tent of rotation of the disc'7 in either direction is positively limited.

Theopposite end portion of the beveled -working face 8 of the disc 7 is continued by 85 fthe disc 7 has been turned tothe limit of its 90 movementin one'direction. Y

Secured by the screws 14 or the like to the innermarginal portion'of the out swinging member of the sash W is an elongated lug 15. 95 This lug 1 5 has a longitudinal marginal portion projecting beyond the adjacent marginal portion of the out swinging member of `the sash and 'said marginal portion of the lug 15 is disposed on an inward bevel 16 com- 10o Y plemental to the bevel of the working face 8 of the disc 7.

Then the window sash W is in its fully closed position, the extended portion of the plate -3 is disposed over the applied lug 15 and upon requisite turning movement of the disc 7 the working beveled face 8 thereof will have close Contact with the beveled face 16 of the lug 15 and thereby effectively hold the sash tightly in its closed position.

The head 6 has pivotally connected therewith, as at 17, an elongated arcuate handle 18 which provides convenient means for effecting the desired rotation of the head 6 and the associated disc 7 for holding or releasing the window sash as desired. In this operation, the handle 18 may be readily swung outwardly to assure an effective leverage action.

In applying the screen to the frame F said screen may have produced therein a suitable opening 19 through which the head 6 will be disposed. In applying or removing the screen S the handle 18 may be readily swung into a position constituting substantially a continuity of the outer end of the head G, said handle 18 being disposed lengthwise on a curvature to permit the screen S to be readily swung upon its lower edge as a fulcrum.

yn iodiication Without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice'except as hereinafter claimed.

I claim 1. In combination with a window frame and a sash coacting therewith, a plate secured to a member of the frame and disposed inwardly thereof, said plate overlapping a marginal portion of the sash when the sash is in closed position with respect to the frame, a fastener member rotatably carried bythe extended portion of the plate, means carried by the portion of the sash adjacent to the member of the -frame carrying the plate with which the fastener member is engageableto hold the sash in closed position with respect to the frame, and coacting means carried by the extended portion of the plate and the disc for limiting the movement of the fastener member in opposite directions.

2. In combination with a window vframe when closed. i

and a sash coacting therewith, a plate secured to a member of the frame and disposed inwardly thereof, said plate overlapping a marginal portion of the sash when the sash is in closed position with respect to the frame, a fastener member rotatably carried by the extended portion of the plate, said fastener member having a beveled marginal portion constituting a working face, and a member carried by the window sash and having a marginal portion beveled complemental to the beveled working face of the fastener member and with which said beveled Working face of the fastener member engages upon turning movement of the fastener member in one direction to lock the sash in closed position with respect to the frame.

3. A easement Window fastener comprising a plate adaptedto be connected to a window frame with an end portion extending within the light area of the frame to overlie a window sash when the sash is in closed position with respect to the frame, and a fastener member carried by said end portion of the plate for holding engagement with the sash 4. A easement window fastener comprising a plate adapted to be connected to a window frame with an end portion extending within the light area of the frame to overlie a. window sash when the sash is in closed position with respect to the frame, a fastener member carried by said end portion of the plate-for holding engagement with the sash when closed, said fastener member being at the side of the plate opposed to the sash, and means at the opposite side of the plate for operating said fastener member.

5. A easement Window fastener comprising a plate adapted to be connected to a window frame with an end portion extending within the light area of the frame to overlie a window sash when the sash is in closed position with respect to the frame, a shank disposed through and rotatably supported by said end portion of the plate, a fastener member at one side of the plate and rotating with the shank, said member upon rotation of the shank in one direction being engageable with the sash to hold the same in closed position, and an operating handle for the shank at the opposite side of the plate and pivotally connected to the shank.

6. A latching means adapted for use with disc is in a second position, the axis of the disc being disposed in the same general direction as the swinging movement of the member, and an operating member hingedly connected with the shank at the side of the support remote from the disc.

In testimony whereof I hereunto aix my signature.

THEODORE JOHNSON.
